    v1 v1  
     1Adding a new OS disk images to XVM installable as HVMs is quite simple:
     2simply download a trusted ISO of the os, create the image from it, and add the image to the database.
     3
     4note: see http://linux.die.net/ for man pages you don't have installed locally.
     5
     6I'll walk through the process with Fedora 14 as an example.
     7
     8{{{root@aperture-science:~# wget http://mirrors.mit.edu/fedora/linux/releases/14/Fedora/i386/iso/}}}
     9
     10
     11{{{root@aperture-science:~# du -sh Fedora-14-i386-DVD.iso}}}
     12
     13In this case we find that the image is 3.5G, which we need to know to create the logical volume in the volume group named xenvg.
     14
     15{{{root@aperture-science:~# lvcreate -n image_fedora-14-i686 -L 3.5G xenvg}}}                       
     16
     17Having created the space in the volume, we now need to place the image in it, reading from the ISO.
     18
     19{{{root@aperture-science:~# dd if=Fedora-14-i386-DVD.iso of=/dev/xenvg/image_fedora-14-i686 bs=4M}}}
     20
     21and then just clean up the old image   
     22{{{root@aperture-science:~# rm Fedora-14-i386-DVD.iso}}}
     23                                         
     24In order to allow users to install a copy of Fedora 14 from the web interface, invirt-web, and consequently invirt-database need to know about it.
     25We simply enter it into the database using the postgres shell on xvm.
     26
     27{{{root@xvm:~# sudo -u postgres psql invirt}}}
     28 
     29
     30{{{invirt=# insert into cdroms values ('fedora-14-i686', 'Fedora 14 (i686)', 'fedora', '14/Fedora')}}}
     31
     32{{{invirt=# \q}}}
     33
     34{{{root@xvm:~# exit}}}
     35
     36
     37
     38Adding new Autoinstalls is somewhat more complicated.
     39Someone (quentin?) should fill in what is required to do that.
